USNCO美国化学奥赛辅导课程

考试内容

USNCO美国国家化学奥赛难度介于中学化学和大学化学之间,知识点全面,且以无机化学为主。相比AP化学,USNCO在分子轨道,酸碱平衡,能斯特方程当方面难度加大,对于AP化学中的有机,生化弱项,USNCO亦有要求,总体无机部分占比90%左右,其余为有机和生化部分。此次USNCO课程不仅仅针对USNCO首轮,我们会增加有机内容,对美高学员有额外帮助(美高学员可以晋级第二轮USNCO National),除了冲击奖项外,同样适合AP,IB,Alevel课程学员的学科考试。

适应对象

USNCO美国化学学会 (ACS) 主办,是美国极具影响力的高中化学竞赛

此次USNCO,所有对化学感兴趣的学生均可参加,特别是准备申请美国理工科专业,以及准备明年AP化学大考的学生

课时:50小时
